✅ FREE SHIPPING
Take your grading game to the next level with the Gem10®️ Leveling Tools—the only tools specifically designed to measure both the leveling and centering of your trading and sports cards. Whether you're submitting to PSA, SGC, BGS, CGC, TAG, or another top-tier grader, these tools help you make confident, informed decisions before you send.
🔍 Why You Need the Gem10®️ Leveling Tool
The Gem10 Leveling Tools combine two precision measuring instruments in one:
-
A millimeter-based leveling grid for accurate edge-to-edge analysis
-
Dual rulers, printed directly into the laminate for all-in-one measurement functionality
These aren’t your average flimsy plastic guides. Crafted from durable, thick laminate, they’re built to last—rounded corners protect both your cards and your hands, and an extra laminate overlay preserves the printed measurements and ensures long-term performance.
🧠 Go Beyond Centering – Discover Hidden Print Defects
Gem10 pioneered the concept of leveling measurement—a tool not only to check if your card is centered, but also to identify subtle misalignments or defects across the card’s printed layers.
This tool lets you:
-
Measure centering and leveling of both the card and its internal design elements
-
Detect print layer shifts and manufacturing defects that are hard to spot with the naked or untrained eye
-
Evaluate borderless cards, which traditional centering tools struggle with
No other grading tool on the market gives you this level of insight.
🛑 Eliminate Costly Grading Mistakes
With the Gem10®️ Leveling Tool, you’ll:
-
Avoid submitting off-center or unbalanced cards that won’t grade a Gem Mint 10
-
Catch flaws you might not see otherwise
-
Save money by only sending in your best, most grade-worthy cards
Whether you’re a new collector or a seasoned pro, this tool makes smart grading decisions simple.
💰 The Gem10 Leveling Tools Practically Pays for Itself
Every time you submit a card for grading, you’re investing more than you might realize—on average, about $26 per card. That includes:
-
Grading fee: $20–$25
-
Postage: ~$1.00 (based on a 20-card submission)
-
Semi-rigid holder: ~$0.50
-
Penny sleeve: ~$0.05
-
Your time and effort: priceless
Now imagine submitting a card that doesn't hit the grade you were hoping for—money wasted. But with the Gem10®️ Leveling Tools, you’ll have the tools to evaluate centering and alignment before you submit. At just $25, if this kit helps you avoid sending in just one low-grade card it’s already paid for itself, and then some.
Grade smarter. Submit with confidence. Save money.
🎨 Choose the Right Tool for Your Cards Coloring (Lighter or Darker)
Traditionally, collectors only had access to black-printed tools—which work great for light cards, but become unreadable over dark or black card designs.
Gem10®️ changed the game by introducing a white-printed laminate to solve this problem.
-
Black laminate is ideal for cards with light backgrounds
-
White laminate offers excellent visibility over dark or black backgrounds
Get both versions—or go all-in with the Gem10®️ King Kit, which includes every black and white leveling and centering tool in the lineup.
